Need it we have them, they are hard to get and its only for the CPI GTR 50 period.
The works great and keeps your CCPI GTR 50 running top notch.

The cylinder head is in two parts so it makes for excellent thermal conditions.
The Stock carb works well when up-jetted to 85-95 with high performance air filter.
The stock exhaust also works well, the GTR is a well made bit so the stock parts are worth it but a high performance pipe such as a Yansani would be great addition.
